Abstract

1437116 Polyamide fibres BAYER AG 4 Oct 1973 [4 Oct 1972] 46413/73 Heading B5B [Also in Division C3] Threads are wet- or dry-spun from solutions of high M.W. aromatic copolyamides comprising a 2,4-(1H,3H)-quinazolinedione ring systems. The solvent may be dimethyl acetamide, or N-methylpyrrolidone, or dialkyl sulphoxide. In the wet process, the threads are coagulated in an aqueous bath at 50-60‹ C. In the dry process, the threads are extruded into a shaft charged with air at 200‹ C. The threads from both processes are then prestretched in boiling water to a ratio between 1 : 1À2 and 1 : 1À7, washed in water at 60‹ C., and dried. They are finally stretched to a ratio of 1 : 6-1 : 12 at 420- 500‹ C. The copolyamide comprises 50-95% moles and 5-50% moles II where X is -CONH- or -NHCO-, R 1 and R 2 are H, alkyl, alkoxy, or halogen, R 3 is H, halogen, alkyl, alkoxy, -CN, -COOR 4 , or -CONR 5 R 6 , Ar is an aromatic group, R 4 and R 7 are H or alkyl, R 5 and R 6 are H, alkyl, or optionally halogenated aryl, Y is an aromatic group comprising one or more aromatic rings which may be condensed or joined by a single bond or by -CO-, -CR 7 R 7 -, -O-, -S-, or -SO 2 -, or their alkyl or halogen substitution products. Reference has been directed by the Comptroller to Specification 1,384,984.
